A large gear 4U is mounted upon the shaft 38-and meshes with a gear 4IV causing the stem 42 to rotate, the shaft 20 will v be similarly rotated causing the spring 24 to be wound upon the shaft 20 while the main spring casing remains stationary. A means is also associated-with the winding stem 42 for permitting the hands I1 and I9 to be adjusted for indicatingv 4l which extends at right angles t o the shaft 32 and parallel with the.shaft 38. The shaft 41 is rotatively supported in a pair of brackets 48 contained within the watch casing I0. A geari 49 is mounted on the shaft 41 and is adapted to be engaged' by the gear 4I in a pulled out position `of the winding stem 42, as indicated by the dot and dash lines`42"-in Fig. .9, for permitting the shaft 41 to be rotated to correspondingly rotate the shaft 32 and cause the hands to be adjusted independently of the main spring casing 2I.

' A means is provided for limiting the movement of the winding stem 42 to positions inv which the gear 4I will mesh with either the gear 40 or the gear 49. This means comprises a collar 50 mounted on an intermediate portion ofthe winding stem 42 and which is provided with a pair of spaced grooves 50?. The grooves 50 are spaced from each other a distance equal to the space between the adjacent faces of the gears 40 and 49. A -means is engageable into one or the other of the grooves for maintaining the stem 42 in a position in whichthe gear di meshes with the gear 40 or the gear 49. This means comprises alcasing 5i mounted upon a bracket 52 adjacent the collar 5U. A knob 53 extends from one end of the casing 5i adjacent the collar 5o and engages into one of the grooves 552. A spring54 operates between the inner end of the knob 53 and the other end of the casing 5I for urging thepknob 53 into an extended position.

gear 34 and which meshes with the gear 51 for causing the same to be rotated independent of the control stem 55. y

An alarm spring casing 82 is flxedly mounted upon a bracket 53 mounted upon the bottom plate I2 and spaced from'the gear 51. A telescopic winding stem 84 for the alarm mechanism exspaans tends from the interior of the alarm spring casing 62 to the exterior of thc easing I0. The outer end of the alarm spring stem Il is provided with a knob 65 normally contained within a recess I0e g formed in the back face of the watch casing I0.

When the knob 65 is rotated the spring contained within the alarm spring casing 62 will be tightly wound on the telescopic stem 64. A means is provided for preventing the spring from again unwinding until the pin 58 engages the cam cutout 51, freeing the cam. This means comprises a ratchet wheel 88 mounted upon one end of the telescopic stem 6d. An operator rod 61 has one of its end s rotatively engaged upon the vhub of the gear 51 (see Fig. Il) The other oi' its ends is provided with a pin 8l which is adapted to engage the teeth of lthe ratchet wheel., 66 for holding the stem 64 against rotating until such time as the gear 51 moves forward on the control stem 55 for disengaging the pin il from the teeth of the ratchet'wheel 66. When this pin is disengaged from the teeth the spring quickly unwinds and the end of the telescopic stem 64 which bears against one's wrist rotates therewith indicating that the hour hand I1 has reached the predetermined time indicated by the pointer 56 and that the alarm has gone oi.

The stem 6I is composed of separate sections consisting of a section 6 4* rotatively but nonslidably supported upon the alarm spring casing i2. Asection 64b slidably but non-rotatively engages the end of the section 6I* and is provided with the knob 65. A catch 10 is attached to the lower side of the operator rod 81 and normally engages a ange il for holding the section 64b in position in which the knob 85 will be located within the recess I formed in the watch casing In (see Fig. 3). A portion of the catch slidably engages through a bracket 1I supported on the back plate l2y for holding the operator arm 61 against rotating with the gear 51. When the cam cutout i1l is aligned with the pin 58 and the gear 51 is moved forwards by the action of the spring 60 the catch 10 will be 45 disengaged from the flange 8| and a-means is provided for urging 'the section w into its extended position for more rigidlyv bearing against one's wrist.

- The means .for projecting the section 64 into o its extended position comprises a collar 12 mounted upon the section 64. A spring 13 is coaxially mounted upon the section il and operates between the adjacent face of the collar 12 and the inner end of the section 641 for urging the section 64b into its extended position when the catch 10 is disengaged therefrom. A collar 14 is mounted upon an intermediate portion of the section D and is adapted to strike the inner face of the projection i0 for preventing the section b from. being completely disengaged from the section il* when the catch 1n is disengaged therefrom.

A means is provided for slidably but non-rotatively connecting the section Mb with the sec- .5 tion 64. This means comprises a key 15 mounted within the opening in the section M into which the end of the section "extends and which engages a groove 16 formed in the section Nl. The key 15 is arranged radially of the stem 64.

The ring l5 has raised symbols |51 simulating the hour indications of the watch and which are adapted to be felt in the vdarlr so that said alarm mechanism may be set at a predetermined desired time without light.

`soasiocausethspointerIl.tobealiguedwiththe engaging the ange 64W with the catch 1I and ed in Fig. 11 the individual alarm watch is provided with an alarm winding stem N' having a head 6l' located within a recess ll in the casing of the watch, and a ring il" is hingedly mounted on the head t5' and is adapted to be manually I extended as shown by the full lines in Fig. i1, or to be folded back as indicated by the dot and dash With this arrangement it is possible to wind the alarm by extending the ring il" and then applying rotations. In other respects this i0 form of the invention is similar to the previous form.

'I'he operation of this device is as follows:

The watch crystal frame Il* is rotated about the face oi the casing Il by engaging one's nnger nail against the pointer Il which is integral with the crystal frame I4'L and is formed with the grooveor notch landthisnotch Iiinturnis being engaged by the alarm indicating hand Il",

For setting the alarm mecha- 4nismthesection bofthealarmllispulledmanually outwards for permitting the knob 6I to beA rotated for tightly winding the stem of the spring mechanism 82 tightly upon the stem M. The stem section Mb is manually-urged inwards for the watch is engaged upon ones wrist. When the cam cutout 51l reaches an aligned position with the pin 58 the spring 6U will urge the gear 51 upward disengaging the pin 0I of the operator rod from the teeth of the ratchet wheel il freeing the winding stem Il.' The movement of the operator rod 01 will simultaneously disengage the catch 1li from the flange il* freeing the stem section 64b permitting the spring 1I to urge the said section into its extended position for rigidly bearing against one's wrist for indicating that the alarm has gone off.

The individual alarm watch has an additional use, that of telling time in the dark, or by blind people who will be able to feel the setting of the alarm mechanism. This may be accomplished by moving, which. is in the form of an arrow, across the ring Il so as to change the time at which the alarm is set and moving the pointer until a position is reached in which the alarm operates. This will indicate the time. Then one need only feel the raised indications Il to iigure out the time. After this operation the pointer I6 may be again reset to set the ringing mechanism at' a predetermined time.

A suitable stopper arrangement may also be provided to stop the alarm m While I have illustrated and described the preferred embodiments of my invention, it'is' to be understood that I do not limit myself to the precise constructions herein disclosed and the right. is reserved to all changes and modiilcations coming within the scope of the invention as defined in the appended claims.
